What IS wrong with taking antibiotics, really? Do they do any harm that can't be rectified with a course of probiotics?
That's a million dollar question right there. The bigger question is, do the ends justify the means?
If you're going to take them, do small(-ish) doses of probiotics during the course of antibiotics, ramping up to bigger doses of probiotics when the course of antibiotics are over.
I've personally decided to resort to trying a prescription antifungal for my tinea versicolor skin issue. I'll be doing the same type of probiotic plan as I mentioned above, plus a lot of liver support (Nizoral has a bad history with livers).
My ND buddy (who prescribed the antifungal) and I had a short discussion about this while talking about my issue. Natural remedies are great, but they sometimes lack the "punch" needed to really fix certain problems. Even I'm too lazy/busy to take this certain bath every day for a month to do the natural fix for my issue, so I'm going the Rx route.
Prescription drugs done for short periods with the intention of "solving" an issue (ie. H. Pylori or tinea versicolor) is the way they are used best, IMO.
Taking Rx drugs every day (for a condition likely caused by malnutrition/toxicity/lack of exercise) for the rest of one's life is not the best idea, and would more likely be dealt with better through a more "natural" route.
